Application filed February 13, 1915. Serial No. 7,358.

To all whom it may concern Be it known that I, EDWARD E. Brannon, a citizen of the United States, residing at Hamilton, in the county of Greenwood and State of Kansas, have invented certain new and. useful Improvements in Pneumatic Pumps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to pumps and the primary object of the invention is to, provide a pneumatic pump which is operable by compressed air, for forcing mlater under pressure, from a well, cistern r like retainer, to various parts of a house Another object of this invention is to materially simplify the construction of pumps of this nature, eliminating the employment of floats and the like, and providing manually operable means for controlling the passage of water through or into the pump.

With the foregoing and other objects in View this invention consists in such novel features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the ac companying drawings and claimed. I

In describing the invention in detail reference will be had to the accompanying drawings wherein like characters designate like or corresponding parts throughout the several views, and in which Figure 1 is a side elevation of the improved pump, showing the same inserted in a cistern or well,

gig. 2 is a vertical section through Fig. 1, an

Fig. 3 is a cross sectional view on the line 3-3 of Fig. 1.

Referring more particularly to the drawings, 1 designates a water retaining receptacle, which may be a Well or a cistern, or any other desirable water-retainer commonly in use. If the improved pneumatic pump is attached to a cistern, a water supply pipe indicated at 2, is provided for feeding the water into the cistern or receptacle.

Atank 3, which is substantially cylindrical shaped, is positioned centrally within the cistern or retainer 1, and extends upwardly therein having its upper end positioned a short distance downwardly from a floor or platform 4 of the receptacle. The tank 3 is held in its proper position against movecating with the interior thereof, and extend.

ing upwardly through the removable top. 8 of the tank. The pipe 6 may be connected to any desired means, such as a compressed air storage tank or a compressed air pump,

for supplying air under pressure to the 1nterior of the tank 3. A valve 9 is interposed in the pipe 6 for controlling the passage of air therethrough. I

The pipe 7 is provided for permitting of the exhaust of air out of the tank 3, and it has a valve construction 10 interposed therein for controlling the passage of the air outwardly therethrough.

The tank 3 has a water inlet opening 12 formed in one side thereof adjacent its lower end, to which inlet opening is connected a pipe 13. A. valve 14, is provided for controlling the passage of water through the pipe 13 and into the tank. The valve 14 has an arm 15 connected to the valve stem 16 thereof. A rod 18 is connected to the arm 15 and extends upwardly through the receptacle 1 and outwardly through the top or platform 4 of the same, having a .handle 19 mounted upon its upper end to provide for the manual manipulation of the rod 18 for controlling the passage of water through the valve 14.

The receptacle 1 and the tank 3 are provided with openings 20 and 21 extending therethrough respectively, a short distance downwardly from their upper ends. The openings 20 and 21 are positioned in alinement with eachother and have extending therethrough a conduit 22. The conduit 22 extends into the tank 3 and is bent upon itself, forming a downwardly extending section 23, which extends downwardly sub-. stantially at right angles to the horizontal portion of the conduit.

The vertically disposed end 23 of the conduit 22 extends downwardly within the tank 3, and is positioned centrally therein, having an opening 24 formed therein, a short distance upwardly from the lower end of the pipe or conduit. The opening 24 is provided for permitting of the inlet of water into the conduit 22, from whence it passes or is conveyed to any suitable location.

In the operation of the improved pneuy it is desired to force water through the matic pump heretofore described: When conduit 22 under pressure, the valve'l is operated, by manually moving the rod 18,

which opens the valve 14: and permits Water to flow into the tank 3. WVhen the valve 1 L is opened, the valve is also opened, to

permit of the escape of the air out of the tank 3, upon the rising of water therein.

After the tank has been properly filled, the valves 10 and 14 are manually closed, but the valve 9 is opened, for admitting air into the tank 3, under pressure. The air entering the tank 3 under pressure Will force the water contained in the tank upwardly and out through the conduit 22 to the desired location. i

The platform 4 of the receptacle 1 and the cover8 of the tank 3 are removable, so that access may be gained to the interior of the receptacle-in the tank for the purpose of cleaning them, maintaining the sanitation thereof.

From the foregoing description taken in connection with the accompanying drawings the advantages of construction and of the method of operation of the improved pump will be readily apparent to' those skilled in the art to which this invention appertains and, while in the foregoing description, the principle of the operation of this invention has been described together with various features of construction, it is to be understood that certain minor features of construction, combination and arrangement of parts may be altered to suit practical conditions provided such alterations are comprehended within the scope of what is claimed.

What is claimed is A pump, an outer tank or receptacle, a water supply pipe secured to and comasc oae municating with said receptacle adjacent the upper end thereof, a removable cover secured to the upper end of said receptacle, an inner tank positioned Within the outer tank and resting upon the inner side of the bottom wall thereof, and means for rigidly securing the inner tank to the Walls of the outer tank concentrically related thereto, pipes extending through the cover into the .inner receptacle and communicating therewith, means for controlling passage through these pipes, said inner tank provided adjacent its lower end with an inlet opening, a pipe arranged in said inlet opening and communicating therewith, a Valve arranged in said pipe, an arm connected with said valve, a rod connected With said arm and extending upwardly through the removable cover of the outer tank and its outer end constituting a handle whereby the valve may be operated for controlling the supply from the outer tank into the inner tank, said outer and inner tank provided adjacent their upper ends With alined openings the conduit extending through said openings having one end positioned at the inner tank with its opposite end located on the EDl/VARD E. RARDON.
